The SparkFun ADXL313 Breakout is a low power, high resolution (up to 13-bits) 3-axis accelerometer for measurement up to ±4g. This breakout measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Digital output data is formatted as 16-bit two's complement and is accessible through the on-board Qwiic connectors (I2C) or SPI.
The ADXL313 Breakouts high resolution and low noise enable resolution of inclination changes of as little as 0.1deg, while a built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025deg of inclination. The integrated 32-level FIFO can also be used to store data to minimize host processor intervention, resulting in reduced system power consumption. Additional low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
High Resolution (up to 13-bit)
Low Power: Less than 300 µA at maximum data rate; 0.1 µA in Standby Mode
Low Noise: (150 μg/√Hz)
Built-in Sensing Functions: Activity (presence of motion) & inactivity (absence of motion), user defined acceleration level on any axis, functions can be mapped to interrupt pins, 32 level FIFO for reduced processor intervention & system power consumption
2x Qwiic Connectors
SPI available on PTH header pins (3-wire and 4-wire modes)
